APPARATUS FOR ELECTBIGA'LLY TREATING .AIB AND OTB EB GASES To all whomit mag comm:

Be it known that I, JAMES Howm BRIDGE, a subject of the King of England,but having declared my intentlon of becoming a cit1- zen of the UnitedStates, and now-residing at the city of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania,

I electrically treatingai'r or other have invented certain new anduseful Improvements in Apparatus forv Electrically" Treating Airand-other Gases, of whichthe followrng 1s a specification.

rMy invention has relation to means for in such connection it relates tovarious forms of ozone-producing a paratus ada ted for.

the conduct of the mo e of electrica, y treating 'air or other gases asdescribed and claimed in United States Letters Patent granted to meunder the .No. 832,767 dated October 9th, 1906.

f In particular the present invention relates to ozonlzing apparatus,comprising means for conducting air or other gases transversely throughan electrode, in finely divided Y streams substantially in the path ofmultitudinous electric dlscharges, so that each minute air streamissurrounded by one or more electric discharges, to insure an intimatecontact, of the an orother gases with such electric discharges. Theprinci al ob ects of. m present invention are, rst, to convert t e oxyen of the air into ozon'e by means of ane ectric discharge, or to modifyother gases by conductin the same from one side of a perforate means tothe other side through the perforations, thus projecting or drawing themsubstantially .into the electric discharges passing between suchperforated means and other'means; second to guide the air or other gasso that the same 15 subdivided into smallstreams, and each stream passedsubstantially into the path of'electric discharges at the place on theelectrode near where the ,discharges originate; third-,to so wadjust theelectrical means that discharges takeplace thereon at points surroundingthe perforations through which air or gas is sopassed, in minutestreams, so that each stream passes substantially into the core of'adischarge; fourth, to interpose bafiies, checks or other guides in theair or as currents,-to prevent their reaching the dischargin surfaceofan electrode, except throng the perforated body of such electrode and tocause such air c'urrentsto pass into and out Application filed April 80,

of discharges occurrin thereon; fifth, to

pass the air or gas'in ne streams through the perforations of anelectrode directly into the core of multitudinous discharges originatinthereon, and then to lead it out of the in uence of the discharges bypassing:it through perforations of the same electrode or of an opposinelectrode; sixth, to sassair or other gas a ong the surface of. a

ischarging electrode so as to draw additional air or gas, by as iration,through perforations in the said e ectrode from the ses; and

opposite side thereof, to be o'zonized; seventh,

to prevent the formation of arc and spark discharges in .an ozonizer,comprising one or more perforated electrodes, by interposing adielectric body between said electrodes;

and eighth, to place in the electric current of an ozonizercomprisingone or more perforated electrodes, means for preventing the-formation ofarcs and sparks, and substantially restricting the apparatus to theproduction of the silent brush discharge.

The nature and scope of my present in.- vention will be understood byreference to the accompanying drawings, forming part vention, inapplication.

Referring to the drawings with reference to Fig. 1, l is a tubularperforated electrode within a containing electrode 2, near which adielectric body 3, is placed. The perforated electrode 1, is closed at4, so that air or gas admitted at the open end 5 is forced through theperforations 6, and after passing through the electric dischargest-akingplace near the-rims of said perforations, escapes at 7, asindicated'by the arrow. The course of the air may be reversed, by simplyrunning thesame in opposite directions as will be apparent from thearrangement of .parts in said figure.

With reference to Fig. 2, 2 is a tubular perforated electrode, inclosinga similar tubular-perforated electrode 1. .Air passes perforatedelectrode 1.

in at 5, and flows through the perforations 6, directly into thedischarge passing between the electrodes 1 and 2, and then passes out ofthe discharge througliethe perforations 8. At the points marked 3'and{1, are

bodies interposed to prevent the passage of air or gas, except-asindicated. It is also apparent that the course of the air streamsthrough the apparatus of'this figure may be reversed.

With reference to Fig. 3, 1 and 2 are perforated electrodes properlyinsulated by in-' perforations 6, to be electrified by the dis- 1charges passing between the electrodes 1 and 2, and escapes ozonized at7. Air entering at 5, draws additional air by aspiration through theperforations 6, in the electrode 1, from the inner or under sidethereof.

With reference to Fig. 5, 1 is a flat perforated electrode separatedfrom an opposed electrode 2, by an insulating body 3, which .also servesto prevent the admission of air or gas to the dischar es passing between1 and 2, except througi the perforations 6. After ozonization the airescapes at 7.

Withreference to Fig. 6, 2 is an electrode opposed to a perforatedelect-rode 1, and separated therefrom by an insulating body 3, Air ispassed through the opening 5, into the discharges passing between 1 and2, and out of the samehy the perforations (l, and emerging from theapparatus at 7. The

respective positions of the electrodes may be reversed.

With reference to Fig. 7, 1 is a perforated electrode inclosed by asolid electrode 2, which also forms part of a chamberlO, con-. taining acooling fluid. The electrodes in each of the foregoing cases, may befiat, curved or tubular.

With reference to Fi s. 8 and 9, 6 are perforations, which may he used,in carrying out one of the features of my present invention. Inparticularly Fig. 8, the perforations 6, are surrounded by elevatedpoints.

or projections, at the terminals of which electric discharges occur,when the apparatus;1s in action. In particularly Fig. 9', is

indicated a wire-gauze, the openings 6, of

which serve the function of perforations, while the," raised metallicparts adjacent thereto, serve as points of discharge for the electriccurrent passing between said gauze and'a second electrode, not shown.

With reference-to Fig. 10, the ozonizingapparatus previously describedis shown asstruction may be placed in the circuit at this point toregulate and equalize the current. In the ozonizer 15, the silent brushdischarge is produced, and polymerizes the oxygen passed into itsinfluence through the perforations of the electrodes already described.t V

The use in the circuit supplying ozone apparatus of condenser to raisethe voltage and resonator or choke-coils -to multiply the electricalvibrations, or to regulate the current, is old in the art, and no claimto novelty is here made in this connection; but their application tocontrolling or regulating dis charges passing between perforatedelectrodes of the land herein described is new, and the claim to noveltyherein made is in respect to this combination. I

The operation of the apparatus hereinbefore described is the same as toall the different forms ofsuch apparatus, whether theair or gas isdrawn, sucked or forced through parent to those skilled i the art towhich this invention appert-ain without further description of suchoperations.
